LADDER STOOL.

Application filed April 17, iaie. No, 707,218.

To all whom it may concern:

Be it known that I, GEORGE H. BUGELL HAGEN, a citizen of the UnitedStates, and a resident oi Minot, in the county of Ward and State oiNorth Dakota, have invented a new and useful Improvement in LadderStools, or" which the following is a full, clear, and exact description.I I

My invention relates to improvements in ladder stools, and it consistsin the combinations, constructions, and a-rrangementsherein describedand claimed.

An object of my invention is to provide a ladder stool of the typedescribed, which when in operative position is-rigidly braced so as toprevent the collapsing of the device.

A further object of my invention is to provide a device-of the typedescribe in which the seat portion and the auxiliary legs maybe foldedinto a compact position so as to permit the device to be disposed in, a:small out-of-the-way place. I V

A further object of my invention is to provide a device of thetype-described, which is simple in construction, and which is durableand efficient for the purposeintended.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which Figure 1 is a perspective view of thedevice, and

Figure 2 is a vertical section through the device a-s'shown infoldedposition.

In carrying out my invention, I provide a step ladder portion A, a seatB, and sup-,

porting legs 0. The step ladder portion A consists of side members 1 andsteps 2. The steps also act as reenforcing members for the 7 stepladder.

The seat B comprises a body portion 3 and angle irons 4. As clearlyshown in Figure 2, the angl e irons 4 are pivotally secured to the upperends of the side pieces 1. The

supporting legs 5 are operatively connected to the pieces 1 by means ofa mechanism shown inFigure 2. The bars composing this mechanism arearranged so as to provide a solid support-to the device when the deviceis in operative position. The supporting legs 5 when inextended positionbear against the under side of the horizontal 'io'the supporting legs 5()if connecting members, each set being comthe upper end of ii: ges ofthe angle irons porting the seat portion 3.

The n'iechanism that connects the pieces 1 4 and" aid in sup posed of alink 6 that is pivotally secured to cured at its other endto a link 8 at9. The link 8 in turn is pivotally secured to the rear leg 5. Itshouldbe noted that twoiinks (3 and two links 8 are provided, these linksconnecting the pieces 1. with the legs 5 in the manner just described.An arm'9 is pivotally secured to the angle irons ,4 at 10 and has itsfree end pivotally secured to, a

link 11 at 12. The pins are carried by the comprises two sets L118piecel at 7 and is serear legs 5 and therefore connect the links 9 and11 to the rear legs 5. The links 6 and 11 are in turn pivot-ally securedto each other at 13. A link 14 connects the link 11 to the piece 1 inthe same manner as the link 8 connects the link 6 to the leg 5. The link14 is pivotally secured to the link 11 at 15' and is pivotally securedto the piece 1 at 16.

From the foregoing description of the various parts of the device, theoperation there'- of may be readily understood. When the device is infolded position, the mechanism that connects the legs 5 to the ladderportion A assumes the position shown by the full lines in Figure 2 ofthe drawings. When the legs I 5 are swung away from the ladder portionA, the various arms'and legswill swing into the dotted line positionshown in Figure 2, and thus rigidly support the device in operativeposition. It will be noted from the drawing that the links 8 and 14aredisposed substantially in alignment with eachother when the device is inoperative position, This construction prevents thelegs 5 from accidentalmovement inwardly toward the ladder portion 8. In like mannenthe arms 9are disposed substantially parallelwith' 5 from moving toward the planeparallel with the plane of the ladder portion A. It will thereforeappear that the device when in inoperative position takes up very littlespace. The legs are held apart by the rungs 17 in the same manner as thepieces 1 are held apart by the steps 2.

The steps 2- and the seat 3 permit the device to be used as an ordinarystep ladder. The device is also of snoh a height that it is adapted tobe used as a kitchen stool. The device is very simple in constructionand makes use of a novel means for bracing the legs 5 so as to preventthe accidental movement of the legs while tiie device is being used.

I claim:

1 A ladder stool comprising a ladder portion, a seat pivotall; securedto said ladder portion, supporting legs for said seat and meansincluding links connecting said ladder portion, seat, and legs together,said means being adapted to swing said ladder port-ion, seat, and logsinto parallel relation with respect to each other, and to swing saidlegs away from said ladder portion, and into a position to support saidseat, certain of said links being disposed in alignment with each otherwhen said legs are in extended position, whereby said legs are locked inextended position.

2. A ladder stool comprising a ladder portion, a seat pivotally securedto said ladder portion, supporting legs for said seat, links pivotallysecured to each other intermediate their ends and having one of theirends pivotally secured to said ladder portion and one oi said legsrespectively, a second set of links pivotally secured to the free endsof said first named links and having their free ends lpivotally securedto said ladder portion and said leg respectively, said las named linksadapted to be swung into substantial. alignment with each other whensaid le s in extended position, whereby said I are locked in extendedposition.

3. A ladder stool comprising a ladder portion, a seat pivot-ally securedto said ladder portion, supporting legs for said seat, links pirotallysecured to each. other intermediate their ends and having one of theirends pivotally secured to said ladder portion and one of said legsrespectively, said second set of links pivotally secured to the freeends of said first named links and having their free ends pivotallysecured to said ladder portion and said leg respectively, said lastnamed links adapted to be swung into substantial alignment with eachother when said legs are in extended position, whereby said legs arelocked in extended position, and irons connecting said seat to saidlegs, whereby said seat is swung into operative posit-ion when said legsare swung away from said ladder portion.
